Description

차량용 범퍼 유닛 및 그 제조방법{BUMPER UNIT OF VEHICLE AND METHOD FOR PRODUCING THE SAME}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bumper unit for a vehicle,

본 발명은 차체의 경량화를 도모하고, 차량 충돌시 요구되는 안전성을 만족시키기 위한 차량용 범퍼 유닛 및 그 제조방법에 관한 것이다.The present invention relates to a bumper unit for a vehicle and a method for manufacturing the bumper unit for achieving weight reduction of a vehicle body and satisfying safety required in a vehicle collision.

일반적으로 차량에는 정면 또는 후방 충돌에 의한 충격으로부터 차체 내부 및 실내공간을 보호하기 위한 범퍼 유닛이 설치된다. 범퍼 유닛은 차량의 폭방향으로 구비되는 범퍼빔과 차체 결합을 위한 타 부재들이 구비된다. Generally, a vehicle is provided with a bumper unit for protecting the interior of the vehicle body and the interior space from an impact caused by a frontal or rear impact. The bumper unit is provided with a bumper beam provided in the width direction of the vehicle and other members for body coupling.

또한, 차량 충돌로부터 차체를 보호하기 위해서 고강도의 소재가 요구되는 바, 일반적으로 스틸소재가 사용된다. 이에 더하여, 다양한 공법을 통한 고강도강을 형성하여 이를 범퍼빔으로 이용하기도 한다.In addition, in order to protect the vehicle body from a vehicle collision, a high-strength material is required, and a steel material is generally used. In addition, high-strength steel is formed through various methods and used as a bumper beam.

다만, 고강도의 강을 이용하여 범퍼빔을 구성하는 것은 강도면에서는 우수하나, 고중량의 소재인 강을 이용하므로 차체의 중량이 높아짐으로써 주행성능 및 연비효율의 측면에서 문제점이 있다. However, the construction of the bumper beam using the high-strength steel is excellent in strength, but since the weight of the vehicle body is increased due to the use of steel, which is a heavy material, there is a problem in terms of driving performance and fuel efficiency.

이에 따라서, 스틸소재를 대체하여 플라스틱 소재 등 저중량 소재를 사용하여 범퍼 유닛을 구성함으로써 중량을 낮추거나, 범퍼빔에 내부공간을 형성하여 중량을 줄인 범퍼빔 등이 개발되고 있으며, 그 외 다수 기업에서도 지속적으로 범퍼빔 개발에 힘쓰고 있다.As a result, bumper beams have been developed to reduce weight by constructing a bumper unit using a lightweight material such as a plastic material instead of a steel material, or to reduce the weight by forming an internal space in the bumper beam. We are continuously developing bumper beam.

이와 관련하여 한국등록특허공보 제 10-1286685호인 '차량용 범퍼빔 유닛'이 참조될 수 있다.In this connection, Korean Patent Registration No. 10-1286685 'Vehicle bumper beam unit' can be referred to.

그러나, 플라스틱 소재로 범퍼 유닛을 형성하거나 범퍼빔의 내부에 공간을 형성하여 범퍼빔의 중량을 낮추는 것은 연비 효율 및 제작단가 측면에서 우수하지만 충돌에 대한 내구강도가 현저히 떨어져 범퍼 유닛의 성능이 저하되는 문제점이 있다.However, when the bumper unit is formed of a plastic material or a space is formed in the bumper beam to lower the weight of the bumper beam, the durability of the bumper unit is lowered There is a problem.

상기의 배경기술로서 설명된 사항들은 본 발명의 배경에 대한 이해 증진을 위한 것일 뿐, 이 기술분야에서 통상의 지식을 가진 자에게 이미 알려진 종래기술에 해당함을 인정하는 것으로 받아들여져서는 안 될 것이다.It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

본 발명은 차량용 범퍼 유닛(100)의 경량화를 도모하고, 차량 충돌시 요구되는 안전성 향상을 본 발명을 활용함으로써 간단하고 효과적으로 해결할 수 있는 것이다.The present invention can reduce the weight of the vehicle bumper unit 100 and solve the safety improvement required in the event of a vehicle collision simply and effectively by utilizing the present invention.

도 1 내지 2와 같이, 본 발명에 따른 차량용 범퍼빔(200)은 차량 폭방향으로 배치되며 양단이 차체에 결합된 복수의 범퍼빔(200); 합성수지로 성형된 베이스로 구성되며, 베이스에는 차량 폭방향으로 복수의 관통홀(305)이 형성되고, 베이스는 복수의 관통홀(305)을 통해 복수의 범퍼빔(200)에 의해 관통된 범퍼 보강체(300); 및 강화섬유 토우로 형성되고 범퍼 보강체(300)의 외부를 두르는 강화밴드(310);를 포함한다.1 and 2, the vehicle bumper beam 200 according to the present invention includes a plurality of bumper beams 200 arranged in the vehicle width direction and coupled at both ends to the vehicle body; And a plurality of through holes 305 are formed in the base at the base in the width direction of the vehicle and the base is reinforced by a plurality of bumper beams 200 through a plurality of through holes 305, Body 300; And a reinforcing band 310 formed of reinforced fiber tow and covering the exterior of the bumper reinforcement 300.

이를 구체적으로 살펴보면, 복수의 범퍼빔(200)은 차량의 폭방향으로 배치되며 양단이 차체의 양측방에 결합할 수 있다. 본 발명의 범퍼빔(200)은 파이프 형상으로 구상되지만 그 단면의 형상이 다양할 수 있음은 물론이다.Specifically, the plurality of bumper beams 200 are arranged in the width direction of the vehicle, and both ends of the bumper beams 200 can be coupled to both sides of the vehicle body. Although the bumper beam 200 of the present invention is formed in a pipe shape, it is needless to say that the cross-sectional shape of the bumper beam 200 may vary.

또한, 범퍼빔(200)은 바람직하게는 중앙부가 차체 외측으로 돌출되도록 완만하게 휘어진 형상으로 구비되어 공기저항을 최소화하도록 구비될 수 있다. 또한, 도 1과 같이 복수의 범퍼빔(200)은 차량의 상하방향을 기준으로 정렬될 수 있다.In addition, the bumper beam 200 is preferably provided in a gently curved shape so as to protrude to the outside of the vehicle body, so that the air resistance is minimized. 1, the plurality of bumper beams 200 may be aligned with respect to the vertical direction of the vehicle.

이에 따라, 일반적으로 차량의 높이방향으로 소정의 폭을 갖도록 형성되는 종래의 범퍼빔과 달리 복수의 파이프로 범퍼빔(200)을 구성함으로써 범퍼빔(200) 사이의 공간에 소모되는 자재의 소모가 사라지므로, 중량이 크게 낮추면서 차체 경량화를 도모한 것이다.Accordingly, unlike the conventional bumper beam, which is formed to have a predetermined width in the height direction of the vehicle, the bumper beams 200 are formed by a plurality of pipes, so that the consumption of materials consumed in the space between the bumper beams 200 Since it disappears, the weight is greatly reduced, and the weight of the vehicle is aimed at.

한편, 복수의 범퍼빔(200) 사이에 빈 공간이 형성되는 바, 종래와는 달리 주행시의 공기저항이 크게 줄어들어 주행에 있어 연비 효율적인 측면 등이 크게 향상되는 효과를 가진다.On the other hand, since an empty space is formed between the plurality of bumper beams 200, the air resistance at the time of driving is greatly reduced unlike the prior art, and the fuel efficiency is considerably improved in traveling.

또한, 바람직하게는 복수의 범퍼빔(200)은 다양한 공법을 통하여 고강도로 형성된 강을 이용할 수 있다. 이에 따라 동일한 부피와 중량에서도 더욱 높은 강도를 가진 범퍼빔(200)을 구비할 수 있는 것이다.Further, preferably, the plurality of bumper beams 200 can utilize a steel formed with high strength through various methods. Accordingly, the bumper beam 200 having a higher strength can be provided even in the same volume and weight.

한편, 범퍼 보강체(300)는 합성수지로 성형된 베이스로 구성되며, 베이스에는 차량 폭방향으로 복수의 관통홀(305)이 형성되고, 베이스는 복수의 관통홀(305)을 통해 복수의 범퍼빔(200)에 의해 관통될 수 있다.The bumper reinforcing member 300 is formed of a synthetic resin base. The base has a plurality of through holes 305 formed in the vehicle width direction. The base has a plurality of through holes 305, (Not shown).

구체적으로, 범퍼 보강체(300)를 형성하는 합성수지의 종류는 플라스틱, 에폭시 등 다양할 수 있으며, 본 발명의 차량용 범퍼 유닛(100)을 형성하기 위하여 구비되는 복수의 범퍼빔(200)의 수만큼 관통홀(305)이 형성되어, 각각의 범퍼빔(200)을 연결하는 베이스가 된다.Specifically, the synthetic resin forming the bumper reinforcement 300 may be plastic, epoxy, or the like, and the number of the bumper beams 200 provided for forming the automotive bumper unit 100 Holes 305 are formed to serve as bases for connecting the respective bumper beams 200.

복수의 범퍼빔(200)은 차량 충돌이 일어나는 경우, 판상의 범퍼빔(200)을 이용하는 경우와는 달리 범퍼빔(200) 사이의 로드패스가 존재하지 않아 각각의 범퍼빔(200)이 독립적으로 충돌하중을 부담하게 된다. A plurality of bumper beams 200 are arranged such that when a vehicle collision occurs, unlike the case of using the plate-shaped bumper beam 200, there is no load path between the bumper beams 200 so that each bumper beam 200 can be independently The collision load is imposed.

이 때, 경우에 따라서는 일부 범퍼빔(200)에 지나치게 높은 부하가 작용할 수 있는데, 관통홀(305)을 통하여 각각의 범퍼빔(200)이 결합된 범퍼 보강체(300)를 구비함에 따라서 각 범퍼빔(200)의 하중을 상호 전달할 수 있데 되므로, 하중의 분산효과로 충격에 대한 내구성이 상승되는 것이다.In this case, an excessively high load may be applied to some bumper beams 200 as the case may be. By providing the bumper reinforcements 300 with the respective bumper beams 200 coupled through the through holes 305, The load of the bumper beam 200 can be transmitted to each other, so that the durability against the impact is increased by the dispersion effect of the load.

즉, 본 발명의 범퍼빔(200)은 바람직하게는 파이프형상의 복수의 범퍼빔(200)으로 구성되는데, 이에 따라 수반되는 강성저하의 문제를 범퍼 보강체(300)를 구비하여 범퍼빔(200)간의 하중분산을 가능하게 하는 로드패스를 구성하여 해결하는 것이다.That is, the bumper beam 200 of the present invention is preferably composed of a plurality of bumper beams 200 in the form of a pipe, And a load path for distributing loads between the load paths.

또한, 본 발명의 차량용 범퍼 유닛(100)으로 충격이 전달되면 차량 전후방향은 물론 차량 높이방향의 범퍼빔(200) 사이 이격공간으로 범퍼빔(200)이 휘어지는 등 변형이 발생할 수 있는데, 범퍼 보강체(300)는 복수의 범퍼빔(200)과 결합됨으로써 이러한 변형을 일정 부분 방지하여 내구성을 상승시키는데 유리한 것이다.In addition, when an impact is transmitted to the bumper unit 100 of the present invention, the bumper beam 200 may be deformed into a space between the bumper beams 200 in the vehicle height direction as well as in the vehicle longitudinal direction. The body 300 is advantageous to increase durability by preventing a certain portion of such deformation by being combined with the plurality of bumper beams 200.

한편, 핫스템핑 공법으로 형성된 복수의 범퍼빔(200)을 구비하여 범퍼 유닛을 형성하는 경우, 용접열에 의한 취성의 한계초과 문제로 인하여 보강체를 용접식 결합하는 것이 사실상 불가하다. 따라서 보강체를 결합시키기 위하여 일반적으로 범퍼빔(200)은 핫 스템핑 공법을 사용할 수 없는 문제가 있었다.On the other hand, in the case of forming the bumper unit with a plurality of bumper beams 200 formed by the hot stamping method, it is practically impossible to weld the reinforcing members due to the problem of exceeding the brittleness caused by welding heat. Therefore, the bumper beam 200 can not use the hot stamping technique in order to join the reinforcing member.

이에 대하여, 스틸 소재가 아닌 합성수지로 형성되어 용접이 아닌 끼워맞춤식 결합을 이루는 범퍼 보강체(300)를 이용함으로써 취성 문제를 극복할 수 있으므로 범퍼빔(200)을 핫 스템핑 공법으로 형성할 수 있는 이점이 있다.On the contrary, since the brittle problem can be overcome by using the bumper reinforcement 300 formed of a synthetic resin rather than a steel material and forming a fitting type coupling, not the welding, the bumper beam 200 can be formed by hot stamping There is an advantage.

또한, 도 2와 같이, 강화밴드(310)는 강화섬유 토우로 형성되고 범퍼 보강체(300)의 외부를 두르도록 구비된다.Also, as shown in FIG. 2, the reinforcing band 310 is formed of reinforced fiber tow and is provided to surround the outside of the bumper reinforcement member 300.

구체적으로, 강화밴드(310)를 구성하는 강화섬유는 탄소섬유, 유리섬유 등 다양한 소재가 사용될 수 있으며, 복수의 강화섬유가 합쳐진 다발형상의 단위체를 뜻하는 강화섬유 토우를 수회 적층시킴으로써 강화밴드(310)를 구성할 수 있다.Specifically, reinforcing fibers constituting the reinforcing band 310 can be made of various materials such as carbon fiber and glass fiber. By laminating a plurality of reinforcing fiber tows, which means bundle-shaped unit pieces combined with a plurality of reinforcing fibers, 310).

또한, 강화섬유 토우로 구성된 강화밴드(310)를 미리 형성하여 범퍼 보강체(300)의 외면에 밀착시키거나, 강화섬유 토우를 직접 범퍼 보강체(300)에 두르면서 강화밴드(310)를 형성할 수 있는 바, 강화밴드(310) 성형방식은 다양할 수 있다. 또한, 강화밴드(310)는 범퍼 보강체(300)의 외면에 둘러진 상태에서 열융착방식에 의하여 고착될 수 있다.The reinforcing band 310 may be formed by previously forming a reinforcing band 310 made of reinforced fiber tow and closely contacting the outer surface of the bumper reinforcing member 300 or by directly placing the reinforcing fiber tow on the bumper reinforcing member 300 As can be appreciated, the forming method of the strengthening band 310 may vary. In addition, the reinforcing band 310 may be fixed to the outer surface of the bumper reinforcement member 300 by a heat fusion method.

상기한 바와 같이, 범퍼빔(200) 사이에 이격공간을 형성함으로써 다소 취약해지는 내구성을 보완하기 위해 범퍼 보강체(300)를 구비하면서, 범퍼 보강체(300)의 외면에 강도가 높은 강화밴드(310)를 구비하면서 범퍼 유닛으로서 요구되는 내구강도를 충실히 만족시킬 수 있는 것이다.As described above, the bumper reinforcement 300 is provided to improve the durability of the bumper reinforcement 300 by forming a spacing space between the bumper beams 200, 310), and the durability required for the bumper unit can be faithfully satisfied.

따라서, 강도가 높은 강화밴드(310)에 의하여 범퍼 보강체(300)의 강성과 형상유지력을 높이고 차체 경량화를 동시에 꾀할 수 있는 것이다.Therefore, the reinforcing band 310 having a high strength can increase the stiffness and shape retention of the bumper reinforcement 300 and reduce the weight of the vehicle at the same time.

한편, 도 3과 같이, 본 발명의 차량용 범퍼 유닛(100)은 범퍼 보강체(300)의 일면에 격자식으로 배열된 복수의 홈(315)이 형성될 수 있다.3, a plurality of grooves 315 arranged in a lattice pattern may be formed on one surface of the bumper reinforcement member 300 of the vehicle bumper unit 100 of the present invention.

홈(315)의 단면형상은 사각형상 또는 육각 형상 등 다양할 수 있으며, 홈(315)과 홈(315)의 사이에는 상대적으로 리브가 형성된 것으로 볼 수 있다. 바람직하게는, 홈(315)은 범퍼 보강체(300)를 관통하지 않는 수준의 깊이를 가질 수 있다.The cross-sectional shape of the groove 315 may be a square or hexagonal shape, and a rib may be formed between the groove 315 and the groove 315. Preferably, the groove 315 may have a depth that does not penetrate the bumper reinforcement 300.

범퍼빔(200) 사이에서 로드패스를 형성하는 범퍼 보강체(300)는 충분한 부하 전달능력을 구비하면서 차체 경량화를 위하여 일면에 복수의 홈(315)을 구성하되, 필요강도를 충족시키기 위하여 격자식의 배열을 이룸으로써 일부에 발생할 수 있는 응력집중현상을 방지하고, 홈(315)과 홈(315)사이의 리브를 통하여 범퍼빔(200)간의 충격을 흡수 및 전달할 수 있는 것이다.The bumper reinforcement 300 for forming a load path between the bumper beams 200 is provided with a plurality of grooves 315 on one surface for light weight of the vehicle while having sufficient load transfer capability, It is possible to prevent a stress concentration phenomenon that may occur in a part and to absorb and transmit an impact between the bumper beams 200 through the ribs between the grooves 315 and the grooves 315.

따라서, 불필요한 재료소모를 방지함과 동시에 차체 경량화를 이루고, 격자식 배열과 리브의 형성이라는 구조적인 관점에서 필요강도를 충족시키도록 성형하는 것이다.Accordingly, unnecessary material consumption is prevented, and the vehicle body is lightened, and molded so as to satisfy the required strength from the structural point of view, such as lattice arrangement and rib formation.

또한, 본 발명의 범퍼 보강체(300)에서 복수의 홈(315)이 형성된 일면은 차체를 마주하도록 구비될 수 있다.In the bumper reinforcement member 300 of the present invention, one surface of the plurality of grooves 315 may be provided to face the vehicle body.

홈(315)이 구비된 일면이 차체의 반대측에 형성될 경우, 차량 주행 시 평면형상으로 구비된 경우에 비하여 표면의 공기흐름이 원활하지 못하므로 공기저항이 증가하여 차량 주행의 효율이 낮아질 수 있다.When the one surface provided with the groove 315 is formed on the opposite side of the vehicle body, the air flow on the surface is not smooth as compared with the case where the surface is provided in a plane shape when the vehicle travels, .

따라서, 범퍼 보강체(300)의 홈(315)이 형성된 일면은 차체측을 바라보도록 구비함으로써 공기저항 증가를 방지하여 주행효율을 높히도록 하는 것이다.Therefore, one surface of the bumper reinforcement member 300 on which the groove 315 is formed is provided so as to face the vehicle body side, thereby preventing an increase in air resistance, thereby enhancing the traveling efficiency.

한편, 본 발명의 복수의 범퍼빔(200)은 핫스템핑 공법에 의하여 고강도강으로 형성될 수 있다.Meanwhile, the plurality of bumper beams 200 of the present invention can be formed into a high strength steel by a hot stamping method.

핫 스템핑 공법이란 강을 고열에서 성형처리한 뒤 냉각속도를 조절하여 강의 강도를 조절하는 것을 말하는데, 동일한 소재의 강이라도 강도가 특히 높게 형성되므로 본 발명의 차체 경량화 및 요구강도 확보에 유리할 수 있다.The hot stamping method is a method of controlling the steel strength by controlling the cooling rate after forming the steel in a high temperature. Even if the steel is made of the same material, the strength is particularly high. .

핫스템핑 공법으로 형성된 복수의 범퍼빔(200)을 구비하여 범퍼 유닛을 형성하는 경우, 용접열에 의한 취성의 한계초과 문제로 인하여 보강체를 용접식 결합하는 것이 사실상 불가하다. 따라서 보강체를 결합시키기 위하여 일반적으로 범퍼빔(200)은 핫 스템핑 공법을 사용할 수 없는 문제가 있었다.In the case of forming the bumper unit with a plurality of bumper beams 200 formed by the hot stamping method, it is virtually impossible to weld the reinforcing members due to the problem of exceeding the brittleness caused by welding heat. Therefore, the bumper beam 200 can not use the hot stamping technique in order to join the reinforcing member.

이에 대하여, 스틸 소재가 아닌 합성수지로 형성되어 용접이 아닌 끼워맞춤식 결합을 이루는 범퍼 보강체(300)를 이용하여 범퍼 유닛을 보강하는 본 발명의 특성에 따라, 범퍼빔(200)을 핫 스템핑 공법으로 형성하더라도 취성 문제를 극복할 수 있으므로 핫스템핑 공법을 이용한 범퍼빔(200)의 이용이 가능하여 강도 확보에 유리한 것이다.On the other hand, according to the characteristics of the present invention in which the bumper reinforcement member 300 is formed of a synthetic resin rather than a steel material, It is possible to use the bumper beam 200 using the hot stamping method, which is advantageous in securing the strength.

따라서, 범퍼빔(200) 사이에서 이격공간을 확보함으로써 강성이 취약해질수 있는 점을 보완하고자 강도 확보에 유리한 핫 스템핑 공법을 사용하여 동일한 중량과 부피에서도 더 높은 강성을 확보함으로써 차량 충돌시의 안전성을 증가시킬 수 있는 것이다.Therefore, in order to compensate the weakness of the rigidity by securing the spacing space between the bumper beams 200, it is possible to secure higher rigidity in the same weight and volume by using a hot stamping method, It is possible to increase safety.

한편, 본 발명의 범퍼 보강체(300)는 복수의 범퍼빔(200)을 금형에 인서트하고, 범퍼빔(200)의 외면에 사출성형함으로써 형성될 수 있다.The bumper reinforcement 300 of the present invention can be formed by inserting a plurality of bumper beams 200 into a mold and injection molding the outer surface of the bumper beam 200.

구체적으로, 범퍼 보강체(300)를 개별적으로 성형하여 범퍼빔(200)을 관입하는 경우, 범퍼빔(200)이 관입되는 관통홀(305)에는 범퍼빔(200)과의 사이에 불가피하게 공극이 존재하게 되며, 이로 인하여 범퍼 보강체(300)와 범퍼빔(200)의 결합력이 저감되는 문제가 있는 것이다.Specifically, when the bumper reinforcement member 300 is individually molded and the bumper beam 200 is penetrated, a through hole 305 through which the bumper beam 200 is introduced is inevitably formed with the bumper beam 200, There is a problem that the force of engagement between the bumper reinforcement 300 and the bumper beam 200 is reduced.

이에 따라서, 범퍼 보강체(300)는 범퍼빔(200)을 인서트하여 그 외면에 사출성형함으로써, 개별성형에 따른 불가피한 공극 발생을 방지하여 결합부위에서 결합력이 크게 증가하는 유리한 효과가 있다. Accordingly, the bumper reinforcement 300 inserts the bumper beam 200 into the outer surface of the bumper reinforcement 300, thereby forming the bumper reinforcement 300. The bumper reinforcement 300 has an advantageous effect of preventing unavoidable pores due to individual molding,

한편, 본 발명의 강화밴드(310)는 강화섬유 토우가 범퍼 보강체(300)의 외부에 감김으로써 형성될 수 있다.Meanwhile, the reinforcing band 310 of the present invention can be formed by winding the reinforcing fiber tow outside the bumper reinforcement 300.

강화밴드(310)를 구성하는 강화섬유는 높은 강도를 가지는 반면, 섬유의 단절부가 존재하는 경우 부하 작용시 부하가 단절부에 집중되어 쉽게 파단될 수 있다. The reinforcing fibers constituting the reinforcing band 310 have a high strength, whereas when the cut-off portion of the fibers is present, the load can be easily broken due to the concentration of the load in the cut-off portion.

이에 따라, 강화섬유가 소정의 길이로 절단되어 구비되는 단위밴드(310)를 복수개로 구비하여 범퍼 보강체(300)의 외면을 두르는 경우, 각각의 단위밴드(310)마다 섬유의 단절부가 존재하여 실질적인 강도가 낮아지게 되는 것이다.Accordingly, when the outer surface of the bumper reinforcement member 300 is provided with a plurality of unit bands 310 in which the reinforcing fibers are cut to a predetermined length, there is a cut portion of the fibers in each unit band 310 And the actual strength is lowered.

따라서, 범퍼 보강체(300)의 외면에 강화섬유 토우를 단절부 없이 연속적으로 감아 강화밴드(310)를 형성함으로써, 강화밴드(310)를 이루는 강화섬유에 단절부 형성을 방지하여 강한 충격에도 파단이 일어나지 않도록 하는 유리한 효과가 있는 것이다.Therefore, by forming the reinforcing band 310 by continuously winding the reinforcing fiber tow on the outer surface of the bumper reinforcement member 300 without cutting portions, it is possible to prevent the formation of the cut portion in the reinforcing fiber constituting the reinforcing band 310, There is an advantageous effect in preventing the occurrence of the problem.

한편, 본 발명의 강화밴드(310)는 범퍼 보강체(300)와 폭이 동일하도록 형성되어 범퍼 보강체(300)의 외부를 두르도록 구비될 수 있다.The reinforcing band 310 of the present invention may be formed to have the same width as the bumper reinforcement 300 and to surround the bumper reinforcement 300.

강화밴드(310)가 범퍼 보강체(300)의 일부만을 두르도록 형성된 경우, 차량의 충격이 발생하면 강화밴드(310)가 둘러진 부분와 강화밴드(310)가 둘러지지 않은 타부분은 서로 강도와 내구력이 상이하여 범퍼 보강체(300)의 국부적 파손을 유발할 수 있다.When the reinforcing band 310 is formed to cover only a part of the bumper reinforcement 300, when the impact of the vehicle occurs, the portion where the reinforcing band 310 is surrounded and the other portion to which the reinforcing band 310 is not surrounded, So that the bumper reinforcement 300 may be damaged locally.

따라서, 강화밴드(310)는 범퍼 보강체(300)와 동일한 폭으로 형성되어 범퍼 보강체(300)의 외면 중 강화밴드(310)가 둘러지지 않은 부분이 발생하는 것을 방지함으로써 범퍼 보강체(300)의 내구력을 안정적으로 향상시키고 차량의 안전성을 향상시키는 것이다.Therefore, the reinforcement band 310 is formed to have the same width as the bumper reinforcement 300, thereby preventing a portion of the outer surface of the bumper reinforcement 300 from being surrounded by the reinforcement band 310, ) Of the vehicle is stably improved and the safety of the vehicle is improved.

한편, 도 2와 같이, 본 발명의 차량용 범퍼 유닛(100)은 합성수지로 성형되며, 범퍼 보강체(300)에 둘러진 강화밴드(310)의 외면을 코팅하는 코팅층(320);을 더 포함할 수 있다.2, the automotive bumper unit 100 of the present invention further includes a coating layer 320 formed of synthetic resin and coating the outer surface of the reinforcing band 310 surrounded by the bumper reinforcement 300 .

코팅층(320)을 이루는 합성수지는 범퍼 보강체(300)를 구성하는 합성수지와 동일할 수 있으며, 강화섬유로 이루어진 강화밴드(310)는 코팅층(320)의 합성수지에 의하여 함침될 수 있다. 합성수지를 이용함으로써 차량의 경량화를 도모함과 동시에 내구성을 향상시킬 수 있는 것이다.The synthetic resin constituting the coating layer 320 may be the same as the synthetic resin constituting the bumper reinforcement member 300 and the reinforcing band 310 made of the reinforcing fiber may be impregnated with the synthetic resin of the coating layer 320. By using a synthetic resin, the weight of the vehicle can be reduced and the durability can be improved.

강화밴드(310)와 범퍼 보강체(300)는 상호 이종의 소재로 이루어진 바, 결합에 있어서 안정성이 떨어지며, 강화섬유로 이루어진 강화밴드(310)는 섬유간의 고착력이 낮은 상태로 형성될 수 있어 시간이 경과할수록 형상을 유지하지 못하고 강화밴드(310)의 일부가 이탈되는 현상이 발생할 수 있다.The reinforcing band 310 and the bumper reinforcing member 300 are made of different materials. The strength of the reinforcing band 310 is low and the reinforcing band 310 made of reinforcing fibers can be formed in a state of low bonding strength between the fibers A portion of the reinforcing band 310 may be detached without maintaining the shape as time elapses.

따라서, 바람직하게는 범퍼 보강체(300)와 동일한 소재로 형성되는 코팅층(320)을 강화밴드(310)의 외면에 구비함으로써, 강화밴드(310)가 범퍼 보강체(300)에 결합되는 것을 보강하고 코팅층(320)과 강화밴드(310) 및 범퍼 보강체(300)가 일체로서 형성되도록 하여 안정성과 내구성을 향상시키는 것이다.The reinforcing band 310 may be reinforced to be coupled to the bumper reinforcement 300 by providing a coating layer 320 formed of the same material as the bumper reinforcement 300 on the outer surface of the reinforcing band 310. [ And the coating layer 320, the reinforcing band 310 and the bumper reinforcement 300 are integrally formed to improve stability and durability.

또한, 본 발명의 코팅층(320)은 강화밴드(310)가 둘러진 범퍼 보강체(300)를 금형에 인서트하고, 그 외면에 사출성형함으로써 형성될 수 있다.The coating layer 320 of the present invention may be formed by inserting the bumper reinforcement 300, which is surrounded by the reinforcing band 310, into a mold and injection molding the outer surface of the mold.

코팅층(320)을 별개로 성형하여 강화밴드(310)가 둘러진 범퍼 보강체(300)의 외면에 끼워맞추는 경우 결합을 용이하게 하려면 강화밴드(310)와 코팅층(320) 사이에 공극이 불가피하게 필요하게 되고, 접착제 등을 이용하여 결합시켜야만 한다.If the coating layer 320 is separately formed and the reinforcing band 310 is fitted to the outer surface of the bumper reinforcement 300, it is inevitable that the gap between the reinforcing band 310 and the coating layer 320 is inevitably And it must be bonded using an adhesive or the like.

그러나, 강화밴드(310)가 둘러진 범퍼 보강체(300)를 직접 금형에 인서트하여 그 외면에 코팅층(320)을 사출성형하는 것은 공극이 발생하지 않으므로 결합력이 극대화 되고, 코팅층(320)을 사출성형할 때 합성수지에 강화밴드(310)가 함침되어 앵커효과에 의하여 결합력이 더욱 강해지는 것이다. However, when the bumper reinforcement 300 is directly inserted into the mold and the coating layer 320 is injection-molded on the outer surface of the reinforcing band 310, voids are not generated. Therefore, the bonding force is maximized and the coating layer 320 is injected The reinforcing band 310 is impregnated into the synthetic resin during the molding and the bonding force is further strengthened by the anchor effect.

이에 더하여, 바람직하게는 코팅층(320) 성형을 위한 합성수지는 범퍼 보강체(300)를 이루는 합성수지와 동일 소재를 이용하므로 코팅층(320)의 성형시 범퍼 보강체(300)와 일체를 이루도록 상호결합함으로써 전체를 일체화시키는 작용을 할 수 있다.In addition, synthetic resin for forming the coating layer 320 preferably uses the same material as the synthetic resin forming the bumper reinforcement member 300, and therefore, when the coating layer 320 is molded, the synthetic resin bonds with the bumper reinforcement member 300 It is possible to integrate all of them.

즉, 코팅층(320)을 성형함에 있어 범퍼 보강체(300)를 인서트하여 코팅층(320)을 사출성형함으로써 범퍼 보강체(300), 강화밴드(310) 및 코팅층(320)은 상호결합하여 일체화를 이루도록 할 수 있고, 코팅층(320)의 결합력이 극대화 되며, 강화밴드(310)의 안정적인 고착에 유리한 것이다.That is, in molding the coating layer 320, the bumper reinforcement member 300 is inserted and the coating layer 320 is injection-molded so that the bumper reinforcement member 300, the reinforcing band 310, and the coating layer 320 are combined with each other, The bonding strength of the coating layer 320 is maximized, and it is advantageous for stable fixing of the reinforcing band 310. [

한편, 도 1과 같이, 본 발명에서 범퍼 보강체(300)는 복수의 범퍼빔(200) 중앙부에 위치할 수 있다. 1, in the present invention, the bumper reinforcement 300 may be located at the center of the plurality of bumper beams 200. [

복수의 범퍼빔(200)은 상기한 바와 같이 양측 단부가 차체와 결합하게 되어 고정상태를 이룬다. 이 때, 차량의 충돌에 따른 충격이 범퍼빔(200)으로 전달하게 되면 고정된 단부로부터 가장 먼 거리에 위치하는 범퍼빔(200)의 중앙부가 변형되기 쉽다.As described above, the plurality of bumper beams 200 are engaged with the vehicle body at both side ends thereof and are in a fixed state. At this time, when the impact due to the collision of the vehicle is transmitted to the bumper beam 200, the central part of the bumper beam 200 located at the greatest distance from the fixed end is liable to be deformed.

따라서, 범퍼빔(200)의 내구력을 향상시키기 위한 범퍼 보강체(300)는 범퍼빔(200)의 중앙부에 위치함으로써 가장 효율적인 내구성 보강효과를 가질 수 있고, 복수의 범퍼 보강체(300)를 구비하지 않더라도 차량 충돌에 대한 필요강도를 확보하게 되는 것이다.Accordingly, the bumper reinforcement 300 for improving the durability of the bumper beam 200 is positioned at the center of the bumper beam 200 to have the most effective durability reinforcement effect, and is provided with a plurality of bumper reinforcements 300 The required strength against collision of the vehicle can be secured.

한편, 도 4와 같이, 본 발명에 따른 차량용 범퍼 유닛(100)의 제조방법은 복수의 범퍼빔(200)을 금형에 안착시키는 제1안착단계(S100); 복수의 범퍼빔(200)이 인서트된 금형 내부로 합성수지를 주입하여 범퍼 보강체(300)를 성형하는 제1사출단계(S200); 및 합성수지로 성형된 범퍼 보강체(300)의 외부에 강화섬유 토우로 형성된 강화밴드(310)를 두르는 강화단계(S300);를 포함할 수 있다.4, a method of manufacturing a bumper unit 100 for a vehicle according to an embodiment of the present invention includes a first placing step S100 of placing a plurality of bumper beams 200 on a mold; A first injection step (S200) of injecting synthetic resin into the mold into which the plurality of bumper beams (200) are inserted to mold the bumper reinforcement body (300); And an enforcing step (S300) of placing a reinforcing band (310) formed of a reinforcing fiber tow on the exterior of the bumper reinforcement (300) formed of a synthetic resin.

제1안착단계(S100)에서는 복수의 범퍼빔(200)이 인서트될 수 있도록 미리 구비된 금형에 범퍼빔(200)을 안착시킨다. 바람직하게는 복수의 범퍼빔(200)의 중앙부가 안착될 수 있다. 금형의 형상은 범퍼 보강체(300)의 외형과 동일한 캐비티를 가지도록 구비된다.In the first seating step (S100), the bumper beam (200) is seated on a mold provided in advance so that a plurality of bumper beams (200) can be inserted. Preferably, a central portion of the plurality of bumper beams 200 can be seated. The shape of the mold is provided so as to have the same cavity as the outer shape of the bumper reinforcement member 300.
